Display Port to Dual Link DVI to Dell 2414Q

Dell has released the 2414Q monitor and this will be the first time that I am considering such a hi res monitor. What are the issues that I could potentially face if I have never gone beyond 1920x1020 before? All my external monitors have never supported it.

I know that I will need a Display Port to Dual Link DVI cable and that's all I know.

I have 2 Sony Vaios, one with a Nvidia GT540M and another with a Nvidia 400 series GPU. I also have a 7 year old MacBook Pro.
